You can easily point your domain to WordPress.com by following this procedure.
To point a domain, you’ll need:
An upgraded WordPress.com plan on your site (such as a Personal, Premium, or Business plan, etc.)
Have a mapping subscription for your site
Once all requirements are met, the only thing you will need to use these nameservers:
After you copied the values, just change nameservers at your domain’s DNS Zone.
After you specify new NS records, propagation will start, which can take up to 24 hours to fully propagate.
That’s it! Now you know how to point your domain to WordPress.com 😊
If your domain is pointing elsewhere by NS records, your DNS Zone management is moved to the provider you pointed the domain to and should be managed from there
